hi nabnab i have acquired a ps3 which is a DEX machine but is bricked and would like to enter factory service mode, I have tried the psp ps3jig but as i had suspected that will only work for CEX machines running cex firmware, I was wondering if its possible to compile a factory service mode tool for dex machines that can be launched from a psp.

there are programs that allow this to happen but they have to be launched from the ps3's home menu so i was wondering if you could implement this into a jig for dex firmware?

Is the ps3jig really useless?

I was looking up some information about it after noticing that sony had their own ps3 "pandora battery" and came across this about the ps3jig:

What's the main purpose of this?

To enter Factory/Service Mode on your PS3 using your PSP. This is typically used to downgrade your PS3's firmware version to something that supports homebrew/backups, or you can use it to unbrick some PS3s from a firmware flash gone bad (NOT Waninkoko bricks -- only from unsuccessful downgrade attempts).

I was wondering if this would be possible for higherfw consoles, but I'm sure someone would've tested it by then, and that's probably why those other flashers exist.

This is also on that site: AS OF THIS WRITING, THERE IS NO WAY TO EXIT FACTORY/SERVICE MODE ON PS3 FIRMWARE VERSION 3.56, SO DO NOT ATTEMPT TO USE THIS ON PS3 FIRMWARE VERSION 3.56 UNTIL YOU READ OTHERWISE ELSEWHERE!

I haven't read too much news lately over the past year or so, but I don't think I came across anything mentioned being able to enter or exit service mode on ps3 firmwares higher than 3.55. But can it still be done? O_o

My psp gets to USB driver started. then i switch on ps3 power & press on the quickly press eject. after this nothing happens for about 5 mins then the rsod shoes on tv. laser is removed from bd could this be the problem.
